DESCRIPTION OF PREFERRED AND OTHER EMBODIMENTS

In both embodiments, there is provided a mobile phone having an internal detachable printer which includes a separately detachable printhead and ink distribution unit assembly and further a preferably separately detachable paper or other print media supply. The mobile phone printer of at least the first preferred embodiment is of a standard size thereby conferring a high level of convenience during operation. The primary differences between the two embodiments relate to form of the print media and the location of the ink supply.

Turning initially to FIG. 1, there is illustrated the first preferred embodiment printer phone 1 which looks like a conventional mobile phone including an earpiece 2, microphone 3, aerial 4, a series of push buttons 5 and a preferably colour LCD screen 6 for the display of information.

In FIG. 2, the back portions of the first embodiment phone 1 is shown with the battery cover 8 removed so as to reveal a print media stock container 9 from which business card sized cards or sheets 10 are used on which to print images on by a printer unit 12. The print out onto the card can be processed signal information downloaded via the mobile phone 1 such as e-mail or other facilities.

The mobile phone can optionally be equipped with a camera device 13 which can comprise, for example, a CMOS sensor designed to sense and store images on demand so that the mobile phone 1 can effectively act as a camera device for the printing out of images or their capture and forwarding across a mobile network.

In FIG. 3, there is illustrated an exploded perspective view, partly in section, of the first mobile phone device 1 showing more detail of the printer assembly 12 including the printhead assembly 16 and feed means 17. The paper stock container 9 includes a series of cards 10 which are resiliently compressed by means of leaf springs 14. As shown in the other figures, the print media feed means 17 are provided in the form of pinch rollers 18 which are driven by motor 19 via gear train 20 and which is used to drive individual cards 10 to and past the printhead 16. The printhead may form part of an optionally replaceable printhead and ink distribution unit assembly 21 including an ink distribution unit 22 and can be substantially the same as that disclosed in Australian Provisional Patent No. PP6534 entitled “Micromechanical Device and Method (IJ46A)” filed 16 Oct. 1998 the contents of which are hereby incorporated by cross-reference.

The ink distribution unit 22 of this first embodiment includes a series of ink supply reservoirs 23 to 26 which are provided for full colour printing. The reservoir 23 is substantially larger than the reservoirs 22 to 26 and can be utilized to store black ink. It is estimated that the ink supply will be sufficient for printing of approximately 2000 pages at 15% coverage of black or 200 photos of 50% coverage of CMYK. A more detailed view of the printer assembly 12 is illustrated in FIG. 5 with an expanded technical description being disclosed in the aforementioned provisional patent specification.

The mobile phone system can be operated electronically under the control of a series of one or more application specific integrated circuits (ASICS) which incorporate the usual mobile phone capabilities in addition to camera and image processing capabilities. A sample block diagram indicating the electrical interconnections for this first embodiment is shown in FIG. 7. A suitable adaptation of the system as outlined in PCT Patent Application PCT/AU98/00544 filed by the present application can be utilized in the design of the ASIC. Other alternative system designs can be incorporated in accordance with the knowledge of those skilled in this particular field.

Other features/components of the phone device, the function of which will be readily apparent, are identified in the accompanying illustrations by the following reference numerals.

Reference Numeral Feature/component 30 loud speaker 31 camera lens array 32 NiMh Battery 33 Printhead cover molding 34 Paper exit wheels 35 Printhead capping mechanism 36 Telephone PCB with buttons 37 SIM card 38 SIM card ejector 39 Battery contacts

Turning next to FIGS. 8 to 15, there is shown a second embodiment printer phone according to the invention. Wherever possible like reference numerals will be used to denote corresponding features.

The major differences between the two embodiments are that instead of having a card dispenser and printhead with integral ink supply, this second embodiment utilises a replaceable combined paper and ink print roll cartridge. The cartridge can be substantially the same as that described in the applicant's earlier applications U.S. Ser. No. 09/113,073 “Digital Camera System with Integral Print Roll”; U.S. Ser. No. 09/113,053 “Print Media Roll and Ink Replaceable Cartridge”; U.S. Ser. No. 09/112,744 “Anisotropic Rigidity to Reduce Curl in Rolled Media”; U.S. Ser. No. 09/112,823 “Miniature Color Printer using Ink and Paper Cartridges”; and U.S. Ser. No. 09/112,783 “Ink and Media Cartridge with Axial Ink Chambers” the contents all of which are incorporated herein by cross reference.

Another difference resides in the optional inclusion of a scanning facility, which whilst described with reference to the second embodiment, could also be included in the first embodiment, although it is envisaged that in practice this facility is better suited for use with print media in the form of a print roll. Further, the additional space required to accommodate the scanning facility is less of a problem with the second embodiment which by design cannot be as compact as the first embodiment. More details of these different features are described below.

In the second embodiment, the phone casing 50 is configured to receive the paper and ink print roll cartridge 51 via a cartridge hatch 52 formed in the base of the phone. Also provided in the base of the phone are the usual DC in and USB connectors 53 and 54.

In this particular embodiment, the camera device 13 is located on the rear of the phone and is operable via a camera take button 56. The printer phone may also include a scanning head (not shown) in the form of a linear CMOS image sensor which is located within the right hand side of the casing adjacent an image scan path defined by a scanning image slot 57 having an entry 58 in the front of the phone and an exit 59 at the rear of the phone.

As can be best seen in FIG. 15, the paper and ink print roll cartridge 51 is of similar shape to a conventional 35 mm camera film cartridge, having a paper exit 61 which when installed aligns with a corresponding printer exit slot 62 formed in the front left hand side of the phone casing 50. However, the cartridge 51 is substantially longer, as it preferably contains sufficient print media and ink for 36 images, each 100 mm×150 mm, the customary size of a photographic print. The printhead and ink distribution unit assembly 21 is located behind the portion of the base molding identified at 65.

The second embodiment printer phone 1 can also be operated under the control of a series of one or more ASIC chips which incorporate the usual mobile phone capabilities in addition to camera and scanner image processing capabilities. Again, a suitable adaptation of the system as outlined in PCT Patent Application PCT/AU98/00544 filed by the present application can be utilised in the design of the ASIC chip.

In use, the operation of this second embodiment is very similar to that of the first with the exception of the additional scanner facility. Replacement of the paper and ink supply is achieved by simply opening the cartridge hatch 52, removing the old cartridge and inserting a new one. The cartridge includes pierceable ink outlets which engage nozzles on the ink distribution assembly connected with the printhead.

It will be appreciated by a person skilled in the art that numerous variations and/or modifications may be made to the present invention as shown in the specific embodiment without departing from the spirit or scope of the invention as broadly described. The present embodiment is, therefore, to be considered in all respects to be illustrative and not restrictive.
